That's likely beyond the scope of the hCard spec.

Although I think people can become "creative" with figuring out that
kind of information.  Using information like...
- the domain's WHOIS information.
- the number of hCards on a domain.
- whether the hCard is on the homepage or not.
- a comparison of the various hCards out there for the person (to look
for matching data, conflicting data, etc)

etc, etc.

It will probably take some trial and error.... and an observation of
how people are using hCards (today)... to figure out an algorithm that
is "good enough".  (Over time, as people's usage of hCards changes,
you may need to change your algorithm.)

See ya
